Study finds that if two black holes collide, they would
release as much energy as 100 million supernova explosion.
It is not the first time scientists are viewing galaxies
combining, I mean there are billions of galaxies in our ever expanding
universe, but they haven’t seen the end stage of colliding galaxies. The end
stage results to the black holes in the center of each universe smash into each
other, releasing some pretty violent cosmic fireworks that could wrap space time
itself.
The theory which was published in journal nature by researchers
including scientists from Caltech and NASA’s jet propulsion Lab, suggests that
an unusual light signal they are seeing from PG 1302-102, essentially a black
hole emitting light from the super-heated particles swirling around its
gravitational drain --- is being caused by cosmic dance between black holes in
the system, each located less than the length of our solar system apart.
When you look at the emission lines in a spectrum from an
object, what you are really seeing is the information about the speed, whether something
is moving toward you or away and how fast. It’s the Doppler Effect.
If the theory is correct, study co-author George Djorgovski
of California institute told the New York Times that when two black holes
collide, they would release the energy equivalent to 100 million supernova explosion,
which would rip apart the galaxy in which they are floating. The collision would
also release gravitational waves, ripples in the fabric of space time predicted
be Einstein theory of general relativity.
It is so unfortunate for astronomers who are hoping to
witness such an event are out of luck, as predicted union won’t take place for
about another million years, which is super long for human standards. The
universe already knows whether the theory is correct because the light we are
seeing from this system, located in the Virgo constellation, comes from 3.5
billion light years away, meaning what we are seeing right know took place
billions of years ago.
Until someday we will learn to travel through time, not
going to our past or future, I mean travelling through space time, wrapping
space time continuum,. We will continue to wait and see what happened after the
black holes collides and whether the theory was right or wrong.
